The DM-IMU-L1 is a high-performance inertial measurement unit (IMU) integrating the BMI088 6-axis MEMS sensor, which combines a 3-axis accelerometer and a 3-axis gyroscope. It features a powerful 200MHz main control chip and an embedded Extended Kalman Filter (EKF) algorithm for real-time quaternion-based attitude calculation. The module supports multiple communication interfaces, including USB, RS485, and CAN, offering flexible connectivity options for a wide range of applications. With an adjustable output frequency from 100Hz to 1kHz, the DM-IMU-L1 delivers precise and high-rate data output including acceleration, angular velocity, Euler angles, and quaternions.

A distinctive island structure at the base of the sensor chip enhances shock and vibration resistance, improving the durability and reliability of the module under harsh conditions. The integrated heating circuit maintains a stable operating temperature to effectively reduce gyroscope drift caused by thermal fluctuations, eliminating the need for complex full-range temperature calibrations. This makes the DM-IMU-L1 ideal for applications requiring high accuracy and stability in dynamic environments.
